Description

Technical Field

[0001] This utility model relates to the field of coil material processing technology, specifically to a coil material surface treatment pre-coating device. Background Technology

[0002] With the rapid development of industries such as electronics, packaging, and new energy, the requirements for the surface properties of film materials are constantly increasing. Surface coating treatments on roll materials, such as applying functional coatings and adhesives, have become a key process for improving the surface tension, abrasion resistance, adhesion, and other properties of the materials, thereby enhancing the subsequent bonding effect.

[0003] Currently, most small and medium-sized enterprises in the industry still use the traditional method of manually applying coatings to the surface of material strips with brushes. Statistics show that during manual coating operations, skilled workers can only complete about 5-8 meters of material strip coating per hour, far less efficient than automated production equipment. Manual coating also suffers from serious quality inconsistency issues. Due to significant differences in technique, pressure, and brushing speed among different operators, even the same operator may exhibit varying performance at different times.

[0004] Furthermore, manual coating methods are insufficient for large-scale, continuous production. In modern industrial production, the production of thin-film materials is often a batch-based, continuous process. Manual coating is not only inefficient but also difficult to integrate effectively with other automated equipment on the production line, limiting the overall automation level of the production process. Therefore, a pre-coating device for roll surface treatment is proposed to address these technical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a pre-coating device for surface treatment of roll materials, which solves the technical problems mentioned in the background art, where most current surface treatment of roll materials is carried out by manually applying coatings to the surface of the material strip with a brush, which is time-consuming, labor-intensive, and results in uneven coating.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pre-coating device for surface treatment of rolled materials, comprising:

[0007] The frame is fixedly equipped with a paint tank, and a rotatable pre-coating wheel is installed inside the paint tank. The lower surface of the material strip is in contact with the periphery of the pre-coating wheel.

[0008] Two sets of pressure rollers, each rotatably mounted on the frame, are provided. The pressure rollers are located on either side of the pre-coating wheel, and the upper surface of the material strip abuts against the pressure rollers.

[0009] A feeding mechanism, mounted on the frame, supplies paint to the paint tank after the pre-coating wheel has rotated for a preset time.

[0010] In a preferred embodiment, the feeding mechanism includes:

[0011] A storage bin is fixedly mounted on the frame. A feed head, connected to a push-button valve, is located at the bottom of the storage bin and extends into the paint tank.

[0012] An opening component is provided on the pre-coating wheel and connected to the push-button valve to control the opening and closing of the push-button valve after the pre-coating wheel has rotated for a preset time.

[0013] In a preferred embodiment, the discharge height of the feed head is lower than the height of the material strip on the paint tank.

[0014] In a preferred embodiment, the opening component includes:

[0015] A sliding frame is slidably mounted on the frame, and the push-button valve is mounted inside the sliding frame. The sliding frame can trigger the opening and closing of the push-button valve after it slides. A connecting rod is provided on the sliding frame.

[0016] A reciprocating lead screw, rotatably mounted on the frame along its axis, is connected to the pre-coating wheel via a synchronous belt drive mechanism; and

[0017] A movable seat is slidably mounted on the frame along the axis of the reciprocating lead screw and cooperates with the reciprocating lead screw. A push rod is provided on the movable seat, and the push rod can abut against the connecting rod.

[0018] In a preferred embodiment, a positioning rod is provided on the frame, and the movable seat is slidably sleeved on the positioning rod.

[0019] In a preferred embodiment, a baffle is provided on the frame, the baffle is located inside the slide frame, and an elastic element is provided between the baffle and the slide frame.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] When in use, the device involves passing one end of the roll material around two sets of pressure rollers and a pre-coating wheel, and then connecting it to the traction end of the subsequent processing equipment to drive the roll material. During the movement of the roll material, the friction force drives the pre-coating wheel to rotate. As the pre-coating wheel rotates, the paint in the paint tank adheres to the surface of the pre-coating wheel, thus coating the surface of the roll material and completing the surface pretreatment process for the roll material. The entire coating process requires no manual operation and can automatically supply paint to the paint tank at preset intervals through the feeding mechanism. This eliminates the need for workers to frequently monitor the remaining paint in the paint tank, effectively improving processing efficiency and reducing the labor intensity of workers.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0029] Example:

[0030] like Figure 1 , 2As shown, this utility model provides a pre-coating device for surface treatment of roll material, including a frame 1, a paint tank 2 fixedly installed on the frame 1, a rotatable pre-coating wheel 3 installed in the paint tank 2, the lower surface of the material strip 5 contacting the periphery of the pre-coating wheel 3, and two sets of rotatable pressure rollers 4 installed on the frame 1, the pressure rollers 4 being located on both sides of the pre-coating wheel 3, and the upper surface of the material strip 5 abutting against the pressure rollers 4.

[0031] In use, one end of the material strip 5 can be placed between the pre-coating wheel 3 and the two sets of pressure rollers 4. The pressure rollers 4 increase the contact area between the material strip 5 and the pre-coating wheel 3, which improves the coating effect and increases the friction between the material strip 5 and the pre-coating wheel 3, thus allowing the material strip 5 to stably control the rotation of the pre-coating wheel 3 during movement. Furthermore, in some preferred embodiments, when the material strip 5 needs to be bonded to other materials, one end of the material strip 5 and the material to be bonded can be fed into a bonding machine. The bonding machine pulls one end of the material strip 5 to rotate the pre-coating wheel 3. During rotation, the pre-coating wheel 3 coats the surface of the material strip 5 with the coating in the coating tank 2. The bonding machine completes pre-coating and bonding in one step, saving time and manpower and improving processing efficiency.

[0032] like Figure 1 , 3 As shown, in this embodiment, a feeding mechanism is provided on the frame 1. The feeding mechanism supplies paint into the paint tank 2 after the pre-coating wheel 3 has rotated for a preset time. The feeding mechanism includes a storage box 6 fixedly mounted on the frame 1. A feeding head 8 connected to a press-type valve 7 is provided at the bottom of the storage box 6. The feeding head 8 extends into the paint tank 2. An opening component connected to the press-type valve 7 is provided on the pre-coating wheel 3. The opening component controls the opening and closing of the press-type valve 7 after the pre-coating wheel 3 has rotated for a preset time. The opening assembly includes a slide frame 10 that is slidably mounted on the frame 1, a push-button valve 7 that is mounted inside the slide frame 10, and the slide frame 10 can trigger the opening and closing of the push-button valve 7 after sliding. A connecting rod 12 is mounted on the slide frame 10, and a reciprocating screw 13 is rotatably mounted on the frame 1 along its axis. The reciprocating screw 13 is connected to the pre-coating wheel 3 through a synchronous belt drive mechanism. A movable seat 15 is slidably mounted on the frame 1 along the axis of the reciprocating screw 13. The movable seat 15 cooperates with the reciprocating screw 13, and a push rod 16 is mounted on the movable seat 15. The push rod 16 can abut against the connecting rod 12.

[0033] During the rotation of the pre-coating wheel 3, the reciprocating screw 13 can be controlled to rotate via a synchronous belt drive mechanism. Since a positioning rod 14 is provided on the frame 1, the movable seat 15 is slidably mounted on the positioning rod 14. The positioning rod 14 positions the movement of the movable seat 15, allowing the movable seat 15 to slide back and forth on the positioning rod 14 during the rotation of the reciprocating screw 13. When the movable seat 15 slides to one side of the frame 1, the push rod 16 pushes the connecting rod 12, causing the slide frame 10 to slide. This triggers the opening and closing of the push-button valve 7, automatically supplying a certain amount of material without manual feeding, thus preventing a decrease in coating effect due to reduced material. It can be understood that the preset time is the time it takes for the reciprocating screw 13 to drive the movable seat 15 to slide back and forth once.

[0034] like Figure 1 , 3 As shown, in this embodiment, the discharge height of the feeding head 8 is lower than the height of the material belt 5 on the coating tank 2, so as to avoid material splashing onto the side of the material belt 5 that does not need to be coated during the feeding process. A baffle 9 is provided on the frame 1. The baffle 9 is located inside the slide frame 10, and an elastic element 11 is provided between the baffle 9 and the slide frame 10, so that the slide frame 10 can be reset and disengaged from the press valve 7 after the push rod 16 is disengaged from the connecting rod 12, so that the press valve 7 can be automatically closed.

[0035] The specific usage and beneficial effects of this utility model are as follows:

[0036] When in use, the device involves passing one end of the roll material 5 around two sets of pressure rollers 4 and pre-coating rollers 3, and then connecting it to the traction end of the subsequent processing equipment to drive the roll material 5 to move. During the movement, the roll material 5 drives the pre-coating rollers 3 to rotate through friction. As the pre-coating rollers 3 rotate, the paint in the paint tank 2 adheres to the surface of the pre-coating rollers 3, thereby coating the surface of the roll material 5 and completing the surface pretreatment process for the roll material processing. The entire coating process requires no manual operation and can automatically supply paint to the paint tank 2 at preset intervals through the feeding mechanism. This eliminates the need for workers to frequently monitor the remaining paint in the paint tank 2, effectively improving processing efficiency and reducing the labor intensity of workers.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
